[ic] Putting non-products into a Cart -- is this possible?

[fallen at specialty-books.com]

Ed,

Thanks for the word.  Still have some problems however, let me lay it out.

I have added the global database into the catalog.cfg,

ProductFiles   products buyback  # buyback is global

There are no problems with that, but the problem of getting the item into
the cart is still lurking (see below).  Pulling code nearly directly from
the interchange docs I have tried a few ways of getting an item into the
buyback cart:
# through a tag
[order code="[sql-param isbn]" cart="buyback" page="buyback/bb_basket"]
Sell now! </a>
# through a form
<FORM ACTION="[area buyback/bb_basket]" METHOD=POST>
<INPUT TYPE=hidden NAME=mv_session_id value="[data session id]">
<INPUT TYPE=hidden NAME=mv_action VALUE=refresh>
<INPUT TYPE=hidden NAME=mv_cartname value="buyback">
<INPUT TYPE=hidden name="mv_order_quantity" value="1">
<INPUT TYPE=hidden  NAME="mv_order_item"  VALUE="[sql-param isbn]">
<INPUT TYPE=submit name=mv_junk value="SELL HER!">
</form>


I can verify that interchange is trying to get it into the cart, because
the following shows up in the error logs:
[28/May/2004:17:02:04 -0400] demo1
/cgi-bin/ic/demo1/buyback/bb_basket.html Attempt to order missing product
code: 84757743677
So, the problem seems to be in getting the catalog to accept the buyback
table as a products table.  As far as the docs show, I declared it
correctly in the catalog.cfg, but no dice.  Also, I have verified that the
interchange user has the correct permissions on the mysql database. 
Currently, I am just doing the motions so the buyback table is a copy of
the products table, so it can not be a problem with the fields being
disjunct.
Any more ideas or assistance would be much appreciated,
thanks!
